Daylily plant named &#39;dynamite returns&#39;

ABSTRACT

A new and distinct  Hemerocallis  cultivar of the semi-evergreen type is provided. The new cultivar is very floriferous and forms attractive ruffled bright rosy pink flowers displaying substantial substance, and a funnel-shaped form over an extended period of time. In U.S.D.A. Hardiness Zone No. 6, blooming commonly begins during late June and commonly ends during mid-September. The new cultivar displays a plurality of fans and a plurality of scapes per fan. In excess of 30 buds commonly are formed per scape. The new cultivar is well suited for growing as distinctive colorful ornamentation in the landscape.

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hemerocallis plant of the semi-evergreen type, and hereinafter is referred to by the cultivar name ‘Dynamite Returns’.

The new cultivar is the product of a planned breeding program which had as its objective the creation of a new Daylily cultivar that is intended for use as attractive ornamentation in the landscape.

The cross that resulted in the production of the new cultivar of the present invention was carried out in a controlled environment during May, 1998, at Bridgeton, N.J., U.S.A. The female parent (i.e., the seed parent) of the new cultivar was the ‘Romantic Returns’ cultivar (U.S. Plant Pat. No. 13,481) which displays rich magenta colored flowers.

The male parent (i.e., the pollen parent) of the new cultivar was the ‘Red Hot Returns’ cultivar (U.S. Plant Pat. No. 13,499) which displays bright cherry red flowers having a diameter of approximately 12.8 cm on average. Each of the parent plants is registered with the American Hemerocallis Society.

The parentage of the new cultivar of the present invention can be summarized as follows:

‘Romantic Returns’×‘Red Hot Returns’.

The seeds resulting from the above pollination were sown and small plantlets were obtained which were physically and biologically different from each other. A number of such plants were transplanted into the field at Bridgeton, N.J., U.S.A., during June 1999. Selective study during May 2000 resulted in the identification of a single plant of the new cultivar.

It was found that the new Hemerocallis plant of the present invention is of the semi-evergreen type and:

-   -   (a) forms attractive ruffled bright rosy pink flowers having         substantial substance, and a funnel-shaped form,     -   (b) possesses a long blooming season with repeat blooming,     -   (c) exhibits a propensity to readily display a plurality of         fans,     -   (d) readily forms a plurality of scapes per fan over the         flowering season, and     -   (e) commonly forms in excess of 30 buds per scape.

The ‘Dynamite Returns’ cultivar resembles some well-known cultivars, such as the ‘Stella D'Oro’ cultivar (non-patented in the United States) and the ‘Happy Returns’ cultivar (non-patented in the United States) in the sense that it commonly possesses an unusually long and substantially continuous blooming season (i.e., a multiple repeat character) of up to 90 days in U.S.D.A. Hardiness Zone No. 6. Such blooming commonly begins during late June and commonly ends during mid-September. This compares to a bloom period of less than about 30 days for over 99 percent of the hybrid Daylilies that are available in the trade.

As indicated, the ‘Dynamite Returns’ plant exhibits attractive ruffled bright rosy pink flowers that readily can be distinguished from the orange-yellow flowers of the ‘Stella D'Oro’ cultivar, and the medium yellow flowers of the ‘Happy Returns’ cultivar. To the best knowledge of the originator, the ‘Dynamite Returns’ cultivar is the first long and substantially continuously blooming Daylily having flowers that exhibit such a rich pink hue combined with substantial substance.

The new cultivar can form up to 6 or more fans per year. This compares to approximately 6 to 8 fans per year for the ‘Stella D'Oro’ cultivar and the ‘Happy Returns’ cultivar. Most Daylily cultivars form only approximately 2 to 3 fans per year. Also, the new cultivar commonly forms several scapes per fan during the flowering season, unlike most Daylilies that commonly produce only one scape per fan.

Asexual reproduction of the new cultivar by division was initially carried out on Aug. 15, 2000 at Bridgeton, N.J., U.S.A. At the time of such asexual reproduction the original plant of the new cultivar consisted of a clump of six fans that were phenotypically identical to each other. More specifically, the clump of the new cultivar was removed from the field and the fans were divided. It has been demonstrated that the characteristics of the new cultivar are firmly fixed and are well retained following this asexual reproduction.

The ‘Dynamite Returns’ plant has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light, day length, contact with pesticides, etc.

The new cultivar will be marketed by the Assignee under the HAPPY EVER APPSTER trademark beginning in June, 2008.
